First Design

[DarthCrucias]

ok, so this is my first attempt at rendering something in a cad program in probably 10 years. i'd love some feedback. it is also my first attempt with this program. if i did not post everything needed, please let me know, and i will be happy to amend my post.

i was trying to create a submarine from a game that i like to play. i will post a pic of the sub from my phone after i post this from my computer. i am using openscad to make it (yeah, probably a bit ambitious for a first try)light sub.stllight sub.scad

i have included the rendering and the save file. i realize that the code is likely very sloppy. any suggestions on how to improve would be greatly appreciated

edit included the pic from the game

edit remembered another question: is there any way to smooth the surface out? i dont like the straight edges
